The family COLYDIID^ (Col-y-di'i-dae) is composed of 

 small insects which are usually of an elongate or cylindrical 

 form, and are found under bark, in fungi, and m earth. 

 Some of the species are known to be carnivorous, feeding 

 on the larvae of wood-boring beetles. The tarsi are four- 

 jointed ; the tibiae are not fitted for digging, and the first 

 four abdominal segments are grown together on the ventral 

 side. More than fifty North American species are known. 



The family R.HYSSODID^ (Rhys-sod'i-dae) includes only 

 four species, two from each side of the continent. They 

 are elongate, somewhat flattened beetles, with the head and 

 prothorax deeply furrowed with longitudinal grooves. They 

 are found under bark. 



Family CUCUJID^ (Cu-cu'ji-dae). 



The Cticujids {Cn' cu-jids). 



The insects of this family are very flat and usually of 

 an elongate form ; most of the species are brown, but some 

 are of a bright red color. As a rule they are found under 

 bark and are believed to be carnivorous both in the larval 

 and adult states ; but some feed in grain.
